Help Nexus 10 - Auto Power Off Issue


Sep 30, 2021
Hi there,

I hope someone can help me. I recently had to replace the battery in my Nexus 10. I followed a YouTube video and successfully replaced the battery, charged it up and switched on the Nexus 10. OK so far.

Trouble is, the system auto powered-off when the battery was still at about 65%. It only took around 3 hours to fully recharge, and the same thing happened again, at about 65%. That was a few months ago. The system now auto powers-off at about 75%!!

Does anyone know how or where the level at which the system auto powers-off can be reset to a lower value. The "settings" pages are of no help, and neither is the manual. Is there an 'app' for this? Any help would be appreciated. Many thanks.


Thanks mikedt,
Yes, it was a third-party battery (via Amazon). It had the same capacity as the original, I checked. The way the level at which the Nexus 10 auto powers-off rather suggests there is a 'value' in the software somewhere that when it reaches it, the system shuts down. In the same way that UNIX systems can be made to shutdown at a certain date/time. I was hoping that someone might know where that 'value' could be found.

No 'value' setting, as I have ever seen for such a thing on a phone.

There are apps for rooted devices that allow all types of settings like that, but I don't know of any particular shutoff settings.

It sounds more like the percentage being shown is inaccurate due to a failing battery.

It was shutting off at a different value before, and now it shuts off at a higher value.

It looks like being tethered to a charger or an external battery is in this device's future.

Thanks puppykickr,

That last post was very helpful. I'll scan through the 'app store' in the hope of finding something.

Re: 'being tethered to a charger', was the reason I think the original battery failed in the first place. Having used the Nexus 10 whilst it was being charged, on many occasions, I read somewhere after it failed that it wasn't meant to be used like that. The article said not to use the screen while the battery was being charged.

I'll also investigate external batteries. Thanks again.

Older devices sometimes recommended not to use the device while charging.

Nowadays, most say that it doesn't matter.

Again, batteries are made to last 2-3 years, and I have always used a charger if available while using any device.

And these things are basically my sole entertainment.
(Typing that out just now made me realize just how sad that sounds.)

Being as it is, my devices spend an inordinate amount of time plugged in.
I usually get about 2 years out of a battery, less if I forget the device inside a tent during summer or it gets under the covers of my bed.
Heat is a quick destroyer of batteries.

Thanks again, puppykickr,

Would you say that your info & advice applies more to phones? (The Nexus 10 is a 10inch tablet, no SIM card)
So, if you get about 2-3 years out of a battery, do you replace the battery (if so where do you source the new one) or do you just replace the device (with a newer, better model)? Thanks.

My only experience is with phones- but both tablets and phones use the same battery technology- Lithium-ion.
So the physics holds true for both devices.

When a battery is dying or dead, to replace the battery or the device can depend upon multiple things.

How hard is it to get the old battery out and put a new one in?
(Is the device designed to have a replaceable battery? This alone is not always a stopper, but it will increase the difficulty level of battery replacement.)

Sometimes a newer device isn't always a better one.
I count my lucky stars that my 5.1 lasted long enough for me to skip over the entire 6 series (Marshmallow) of devices.
I went from 5.1 right to 7.1.1

7 was markedly better than 5- mostly.
On 5 I could disable all Google apps and all bloatware as well.
That was not possible on my 7.

Anyway, to get replacement batteries, it is important to avoid used batteries and other such junk- so stay away from e-bay.

Amazon has been great so far for me for batteries.

Do not bother looking up your specific device, or even doing a search on Amazon.

Simply take down the model number of the battery (printed on the battery itself) and enter it and nothing else into the search bar of your browser.
Just the number.

Find any relevant results on Amazon and you should be good to go.

Ignore any information about what devices the battery fits or does not fit.
If the model number matches exactly, then it is the same battery.

Thanks again, puppykickr,

That's pretty much what I did. I found the identical part number (SP3496A8H) on Amazon. Chose a UK based company called "KingSener" and ordered the battery, via Amazon. I had watched a YouTube video several times to check out the procedure and followed it precisely. And then back to my first post for what happened next. I'll try emailing KingSener to see if they can help. Thanks again.
